- The present invention relates to spools for tape, ribbon and the likeand lto a protector for enclosing the s ool in a unit assembly.

The principalobJect'of the invention is the provision of a spool andprotector assembly which is simple to manufacture and one wherein thespool is easily engaged in the protector and locked in protectedposition.

Numerous other objects of the inventionl '1 will be apparent as it isbetter understood Vfrom the following description, which, taken inconnection with the accompanying drawing, discloses a preferredembodiment there- Referring to the drawing:

Figure 1 is a perspective View of a spool and its protecting shellshowing the parts in assembled position;

Fig. 2 is a view similar to Fig. 1 illustrating 2 the spool in partiallyinserted vposition Within its protecting shell; and

Fig. 3 is a fragmentary longitudinal section of the enclosing shellillustrating a spool in protected position, the spool being shownpartially in section.

The spool may comprise a tubular core 11 which is preferably formed fromsheet material and has a disc-likehead 12 secured to each end of thecore in a fixed joint such as one provided by interfolding the edges ofcore and head in a double seam 13. The outer edge of the head 12 ispreferably bent over to form an open curl 14. This spool may containadhesive tape 15 or any other suitable material wound on the core 11 inthe usual manner.

A protector shell is provided which comprises an open cylindrical member21 having its parallel end edges bent or spun inwardly to form curls 22,the length of the shell being of a dimension exceeding the length of thespool. Side edges of the cylindrical member 21, designated respectivelyby the numerals 23 and 24 normally spread or spring apart sufficiently(Fig. 2) to permit insertion of l the spool longitudinally of the shell.These edges 23 and 24 can then be closely wrapped together by anoverlapping of the edge 24 on the outside of the edge 23'and in suchoverlapped position the shell completely encloses the spool. Asillustrated in Fig. 3, the curls 22 when the 'shell is in this closedposition, lie closely adjacent the curls 14 of the spool and closelyconfine the spool within the shell preventing longitudinal movementthereof. y A Provi-sion is made for locking the side edges 23 and 24 inoverlapped position. This lock-V ving feature comprises spaced openings25 struck out in the side part 24 and its outer edge is bent upwardlyand over to form a curl v 26. The openings 25 coact with` spacedprojections 27 struck out from the side art 23, as illustrated inFig. 1. Cooperation etween the struck out projections 27 and theopenings 25 hold the cylindrical wall of the shell in tight registrywith the outer wall of the spool heads, the curls 22 of the shellrigidly holding against the curls 14 of the spool, as illustrated.

When it is desirable to gain access to the spool, the shell may beopened by a prying out of the overlapped side part 24 by slight pressureapplied under the curled edge 26 and this unsnaps or releases theopenings 25 from the projections 27. The natural spring in the metal ofthe member 21 returns the-shell into its open position, illustrated inFig. 2, at which time the spool with its tape .may be readily extractedby withdrawing along a longitudinal axis of the shell.

It isthought that the invention and many of its attendant advantageswillbeunderstood from the foregoing description, and it will be apparentthat various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely Aa preferred embodiment thereof.

I claim:

The combination 4of a spool having heads and a core connecting saidheads, and an enclosing and protecting divided metallic shell havingcooperating snap-catch elements, struck from the divided ends of saidshell, the edges of the shell being rigidly supported by said heads, thecatch elements being releasable by prying up the exposed en d of theshell.
